I have.

A cutter 21 having a rotary cutter blade 20 shown in FIGS. 7 to 9 reciprocates on the transport member 1 along a cutting direction H orthogonal to the flow direction G of the above-mentioned multilayer laminate sheet. The plunger 22, which is configured to move and holds the cutter blade 20 of the cutter means 21 in a vertically movable manner, comprises a frame 21a of the cutter means 21.
The ball screw 23 is rotatably driven by a servo motor 25 provided on the frame 21a, and is rotated by an arrow I of the plunger 22. The cutter blade 20 is configured to be able to move in the vertical direction as shown. The frame 21a has a longitudinal shape and the multilayer laminate sheet 100
8 and 9 are provided, and the cutter blade 20 is lowered to cut the multilayer laminate sheet 100. Occasionally, the holding member 30 holds down the multilayer laminate sheet 100 so that a stable operation at the time of cutting can be obtained. The holding member 30
Is provided with a rubber sheet 31 for making it easier to hold down the multilayer laminate sheet 100.

On the upstream side of the conveying member 1, a receiving guide side comb tooth portion 40 having a large number of comb teeth 3b is fixedly arranged, and each of the comb teeth 3b and 3 is engaged with each other. When viewed from the lateral direction, they are configured to overlap as shown in FIG. Therefore, each of the comb teeth 3b and 3 is overlapped with each other in the lateral direction, so that the multilayer laminate sheet 10 is formed.
There is no gap when delivering 0, so that the paper can be smoothly transported without breaking. In addition, this multilayer laminated sheet 1
In the case of No. 00, if the peeling occurs, the problem occurs as described in the conventional example. Therefore, the smooth conveyance can prevent the formation of an air pocket or the like between the layers of the multilayer laminate sheet 100. A belt conveyor 4 having a number of belt portions 41a is provided downstream of the feed-side comb teeth portion 5.
10 are fixedly disposed, and each belt portion 41a has a drive shaft 44a, a drive pulley 44, and a guide pulley 4 driven by a belt servomotor 43 as shown in FIGS.
5, each belt portion 41a is configured to fit between the respective comb teeth 3a, and when viewed from the lateral direction, each comb tooth 3a and each belt portion 41a overlap each other. Becomes When the transport member 1 reciprocates in the direction of arrow F, each of the comb teeth 3, 3b, each of the comb teeth 3a, and each of the belt portions 41a are in the flow direction G of the multilayer laminate sheet.
It does not completely separate in, it is configured to slightly maintain polymerization even when separated from the maximum when viewed from the side, when transporting the multilayer laminate sheet 100, the multilayer laminate sheet 100 always keeps a flat state, It is configured so that slack does not occur.

As shown in FIGS. 12 and 13, a tapered portion 50 is formed on the upper surface of the delivery side comb tooth portion 5 of the conveying member 1 on the slit 6 side, and a fluorine coating is formed on the tapered portion 50. Alternatively, a fluorine surface 51 made of fluorine-coated paper or the like is formed, and this fluorine surface 51 is also formed on the upper surface of the receiving side comb tooth portion 4. Therefore, the multi-layer laminated sheet 100 is placed at the position of the slit 6 by the cutter blade 20.
Of multi-layer laminate sheet 100 after cutting
00A can be smoothly delivered.

The cutter means 21 is provided with an oil tank 60 filled with oil such as silicon oil.
The oil in the oil tank 60 is supplied through a pipe 61 to an oil supply unit 5 attached to the cutter blade 20 in the vicinity of the cutter blade 20 by a holder 52.
3 is formed by a well-known means so as to be supplied at a constant rate per unit time, an oil film is formed on the surface of the rotating cutter blade 20 to prevent adhesion to the multilayer laminate sheet 100 at the time of cutting, It is configured not to occur. The oil supply unit 53 is provided with a felt or the like (not shown) so as to sandwich the cutter blade 20, and the oil is supplied to the cutter blade 20 via the felt or the like.

Next, the operation will be described. First, the multilayer laminated sheet 100 continuously fed from an extruder (not shown) is arranged along the flow direction G of the multilayer laminated sheet in the state of FIG. When guided on the comb teeth portion 4, the conveying member 1 starts moving upward in FIG. At this time, the conveying speed of the conveying member 1 is set to the same speed as the sending speed of the multilayer laminate sheet 100, and the servomotor 9 is controlled by a control unit (not shown). When the transport member 1 moves along the flow direction G of the multilayer laminate sheet, the multilayer laminate sheet 100 can remain stationary on the transport member 1 because the above-described respective speeds are the same, and can stop on the slit 6. Is transported.

In this state, when the plunger 22 is operated, the cutter blade 20 descends and waits, and the cutter blade 20 joins the fixed blade 6A of the slit 6 in the next operation. When the servo motor 25 is operated in this state, the rotating cutter blade 2 is rotated.
0 linearly moves forward in the range of the cutting stroke C _{S in} FIG. 3, and the cutter blade 20 instantaneously cuts the multilayer laminate sheet 100 while rotating at the joint with the fixed blade 6A, so that the multilayer laminate sheet piece 100a becomes each comb tooth. It is sent to the belt conveyor 41 of each conveyor section 41a that has been superimposed with 3a and sent outside. In this case, since each comb tooth 3a overlaps with each belt portion 41a due to the movement of the conveying member 1, the multilayer laminated piece 100a is conveyed without slack or the like, and the cutter blade which rotates in a fixed state even when cutting. Because it cuts at 20, without the conventional turning and peeling,
As shown in FIG. 15, the squareness of the corner can be accurately obtained. In addition, since the transport speed of the belt conveyor 41 is slightly higher than the transport speed of the multilayer laminate sheet 100 before cutting, each cut surface after cutting is prevented from re-adhering, and Laminated sheet piece 1
00a can be separated completely independently.

When the above-mentioned cutting is completed, the leading end 100A of the multilayer laminate sheet 100 is placed on the feed-side comb tooth portion 5 by the tapered portion 50 at the end of the feed-side comb tooth portion 5 from the comb teeth 3. 100 is smoothly guided, and the next cutting is performed in the same manner as described above by the returning operation of the cutter blade 20. In the above-described configuration, the case where the cutter unit 21 is fixed to the transport member 1 has been described. However, the cutter unit 21 may be configured to move at the same speed as the transport member 1 as a separate body. Also, the receiving guide side comb tooth 4
Although the case where 0 is used has been described, a configuration in which the receiving guide side comb teeth portion 40 does not have the comb teeth 3b is also possible.

[0024]

The method and apparatus for cutting a multilayer laminate sheet according to the present invention are configured as described above, so that the following effects can be obtained. That is, the multilayer laminate sheet is placed and transported on a transport member that moves at the same speed as the feed speed of the multilayer laminate sheet that is continuously fed, and the cutter blade that horizontally moves in a stationary state on this transport member. Since the cutting is performed, the production efficiency can be improved more than before without stopping the feeding of the multilayer laminated sheet. Further, since the sheet in the stationary state is suppressed by the holding member and cut by the cutter blade from the lateral direction, the cut surface is not turned up or peeled off, and the yield can be improved. Further, since the tapered portion is formed in the slit portion for cutting, the sheet can be fed without sagging the leading end of the subsequent sheet after cutting. Further, since the oil is supplied to the cutter blade, an oil film is formed on the cutter blade, and it is possible to prevent adhesion that occurs when the sheet is cut. In addition, since the transport speed of the belt conveyor positioned at the last stage is set slightly higher than the transport speed of the multilayer laminate sheet, it is possible to prevent the cut surfaces of the multilayer laminate sheet after cutting from re-adhering to each other. .
